Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* ReviewStrategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview) provides an overview of each diagnostic category.


DTC Descriptor
DTC C0292 00
- VSES Combination Sensor Circuits



Circuit/System Description

The electronic brake control module (EBCM) supplies a reference voltage of 5 volts to the yaw rate sensor/lateral acceleration sensor and the steering angle sensor. The sensor supply voltage is monitored via an internal feedback circuit to the EBCM microprocessor.

Conditions for Running the DTC

* Ignition ON.
* Ignition voltage is greater than 8 volts.


Conditions for Setting the DTC

The EBCM detects that the sensor supply voltage is less than 4.75 volts or greater than 5.25 volts for 1 second.

Action Taken When the DTC Sets

* The EBCM turns OFF the 5-volt reference circuit, until the ignition is cycled.
* The EBCM disables the traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition cycle.
* The driver information center (DIC) displays Service Stabilitrak.


Conditions for Clearing the DTC

* The condition for setting the DTC is no longer present.
* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.


Diagnostic Aids

If the yaw and lateral accelerometer sensor is disconnected, DTCs will set and the EBCM will not provide 5-volt reference.

Circuit/System Testing

1. Ignition ON, observe the DTC information with the scan tool.

• Verify that none of the following DTCs are set, U0100-U0299. If any of the DTCs are set, Refer to Diagnostic Trouble Code (DTC) List - Vehicle (Diagnostic Trouble Code Descriptions).

2. Ignition OFF, disconnect the yaw rate and lateral acceleration sensor connector.
3. Ignition OFF for 30 seconds, test for less than 15 ohms between the low reference circuit terminal 6 and ground.

• If greater than 15 ohms, test the low reference circuit for an open/high resistance. If the circuits test normal, replace the EBCM.

4. Test the lateral accelerometer 12-volt ignition circuit terminal 1 for a short to voltage or ground.

• If all circuits test normal, replace the yaw rate sensor/lateral acceleration sensor, cycle the ignition switch and perform the yaw rate sensor recalibration procedure with the scan tool.
• If the DTC sets again after replacing the yaw rate sensor/lateral acceleration sensor, replace the EBCM.



Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.

* Vehicle Yaw Sensor with Vehicle Lateral Accelerometer Replacement (Service and Repair)
* Yaw Rate Reference Table Resetting (Programming and Relearning)
* Control Module References (Programming and Relearning) for EBCM replacement, setup, and programming
